On the fecundity of Schizothorax curvifrons Heckel from River Jhelum, Kashmir

Abstract

Fecundity  of  Schizothorax  curvifrons  weighing  77-736  g  (total length,  194-411  mm)  ranged  from  4,843  to  31,221  (x11,998).  Relative  fecundity varied  from  25  to  70  (x45).  Per  ant  coefficient maturity  of fishes  (IV-Vl stages  of  maturity) was in  the  range  of  6.9  to  14.0 (x11.3).  Absolute  fecundity  (kg-1  of  the body  weight)  was estimated  to  be  44,437.  It  was  found  that the fecundity  was  better related  to  the weight  than  the length of the fish.  The fecundity  in 2+  year  specimens  was  observed  to  be 4,483  and the  increase was significant with  the advancement  of age.  In  6 years of its life,  fecundity  increased  nearly  to  four  folds i.e  21.461  eggs  per  spawn.
